Projecting a simple circle onto a wall Hi all there. I hope you can give me a help on this one. I just want to project a simple circle onto a wall, but the problem is that I get a distorted circle due to the projector's position (like in the image in attach). Can someone give me a tip please? Therefore I can use the projector in any position but still have the image not distorted. Thank you for your attention. :-) Cheers,

Sorry forgot to attach the image. Here it is.
Try Frz's perspective plugin: http://1024d.wordpress.com/2010/11/09/_1024_perspective-qcplugin/
I've tried to use that patch. But the problem is, if I use a big circle, with 0.9 radius. I can't see the whole circle. And the perpective patch stretches the image. You can see in the composition in attach, that it isn't a perfect circle but an oval figure. =/ And I want a perfect circle.
unfortunately in QC there's nothing like madmapper's built-in circle primitive (which allows to position the circle using its center as a perspective point).
Stupid question- using 1024_Perspective, why can't you use a circle with smaller radius and make the perspective warp compensate for scale?
Madmapper is a great program.
Yes, but the problem was concerning to the circle, because when I connected it to the perspective patch, the circle was oval. But that is due to the position of the corners. I want it to be a 4:3 aspect ratio, and I had forgot that. That's why the circle was oval. But now it's a perfect circle again. :D
